This time it's a bit more complicated, but it'll be easier to do it to the first equation okay?

Answer 3

I think it's C

Answer 4

well if you dont care of the process to the solution, just plug in x = 9 and y = -1/2 and see if the equations both stand true

Answer 5

I did but i gtg thanks her is a medal

Answer 6

Just plug the values in and see if lhs=rhs

Answer 7

Bye!
